Area Measurement<br />
It is essential to know the amount of area that you intend to cover<br />
when applying a pesticide or fertilizer. Turf areas such as home<br />
lawns and golf course greens, tees and fairways should be mea sured<br />
in square feet or acres, depending upon the units needed.<br />
Circular Areas<br />
Rectangular Areas<br />
Area =<br />
π x Diameter 2 (d)<br />
4<br />
π = 3.14159<br />
Area = Length (l) x Width (w)<br />
Example:<br />
What is the area of a lawn that is 150 meters long by 75 meters wide?<br />
Area = 150 meters x 75 meters<br />
= 11,250 square meters<br />
By using the following equation, it is possible to determine the area<br />
in hectares.<br />
Area in square meters<br />
Area in hectares =<br />
10,000 square meters per hectare<br />
(There are 10,000 square meters in a hectare.)<br />
Example:<br />
11,250 square meters<br />
Area in hectares =<br />
10,000 square meters per hectare<br />
= 1.125 hectares<br />
Triangular Areas<br />
Example:<br />
What is the area of a green that has a diameter of 15 meters?<br />
π x (15 meters) 2 3.14 x 225<br />
Area = =<br />
4 4<br />
= 177 square meters<br />
177 square meters<br />
Area in hectares =<br />
10,000 square meters per hectare<br />
= 0.018 hectare<br />
Irregular Areas<br />
Area =<br />
Base (b) x Height (h)<br />
2<br />
Any irregularly shaped turf area can usually be reduced to one or more<br />
geometric figures. The area of each figure is calculated and the areas<br />
are then added together to obtain the total area.<br />
Example:<br />
What is the total area of the Par-3 hole illustrated above?<br />
The area can be broken into a triangle (area 1), a rectangle (area 2)<br />
and a circle (area 3). Then use the previously mentioned equations<br />
for determining areas to find the total area.<br />
Example:<br />
The base of a corner lot is 120 meters while the height is 50 meters.<br />
What is the area of the lot?<br />
120 meters x 50 meters<br />
Area =<br />
2<br />
= 3,000 square meters<br />
3,000 square meters<br />
Area in hectares =<br />
10,000 square meters per hectare<br />
= 0.30 hectare<br />
Area 1 =<br />
15 meters x 20 meters<br />
2<br />
= 150 square meters<br />
Area 2 = 15 meters x 150 meters = 2,250 square meters<br />
Area 3 =<br />
3.14 x (20) 2<br />
4<br />
= 314 square meters<br />
Total Area = 150 + 2,250 + 314 = 2,714 square meters<br />
2,714 square meters<br />
= = 0.27 hectare<br />
10,000 square meters per hectare<br />
144<br />
